使用 Joda 时间将 UTC 偏移量转换为美国时区 [英] Convert UTC offset to USA time zone with Joda Time

问题描述

给定 UTC 偏移量，即 -5，我可以使用 Joda 时间确定美国时区吗?Pacific、Mountain、Central、Easter 之一就足够了.我不能使用 Java 8.

Given a UTC offset, i.e. -5, can I determine the USA time zone using Joda Time? One of Pacific, Mountain, Central, Easter is sufficient. I can't use Java 8.

推荐答案

如果你只有有一个偏移量，那么不，你不能.例如，-5 可以是中部夏令时或东部标准时间.同样，偏移量 -7 可能是太平洋夏令时或山区标准时间.

If you only have an offset, then no, you can't. -5 could be Central Daylight Time or Eastern Standard Time, for example. Likewise an offset of -7 could be Pacific Daylight Time or Mountain Standard Time.

如果你有一个偏移量和一个有效的日期/时间，你可以做出一个很好的猜测——但前提是你假设美国的所有地方都切换到夏令时，并且所有地方都这样做时间 - 但并非完全如此.

If you have an offset and a date/time at which it was valid, you could make a pretty good guess - but only if you assume that everywhere in the US switches to daylight saving, and that everywhere does it at the same time - but that's not entirely the case.
